Lithium abundances are derived by comparing observed and synthetic spectra in the region of Li I line 6707 Å in LTE approximation. The behavior of Li abundances as a function of the effective temperature Teff, age, rotational velocities vsini and chromospheric activity log R’HK is discussed in the context of stellar and galactic evolution.enSolar TwinsLithium AbundanceScatterArticle
